The OAU charter would be reviewed for "effectiveness and functionality" with the aim of setting up an early warning system to forestall wars, Mbeki said on the periphery of the annual OAU summit in Algiers. The special summit proposed by Libyan leader Moamer Gaddafi was to be held on September 6 to 9 in Tripoli and would coincide with festivities to mark the 30th anniversary of the Libyan revolution. Mbeki showed optimism about an end to the armed conflict in the Democratic Republic of Congo, saying there were signals that "the recently concluded peace agreement will go into force". Looking at economic relations between Africa and Europe, the South African President called for "more concessions" on the part of the European Union. He said the main target of economic cooperation should be to promote development in the African nations on the basis of equality. The OAU‘s 35th summit was to end later Wednesday. On Tuesday the leaders of 53 member countries unanimously resolved to isolate regimes which come to power by force of arms and to encourage democracy on the continent. Any regime that mounted a coup d‘etat would not be allowed to join the OAU, would be diplomatically isolated and would not be welcome at OAU summits, a OAU spokesman said. Observers noted however that a large number of governments represented at the summit originally came to power by force of arms.
